Dear Sir, I think I am the proper person to do this job. I live in Shanxi province of China where this is the manufacture center of the glass ware. Here we make all kind of cup, jar, bottle etc. I have the very good factories, I could manage the visit at once if you need to see these factories yourself. And I can send some pictures to you.
I personally do the trading business for over 10 years, I can handle all the works to achieve our muti-success. Let me know if you have any questions.
